[Handicap and quality of life assessment in amyotrophic lateral sclerosis]

Measures of handicap progression alone are insufficient for assessing what a patient experiences. Handicap results from the interaction between a person's disabilities and the social, familial and environmental factors which determine his or her living conditions. Other factors condition quality of life: of these, psychological and existential factors and an individual's ability to adapt play a fundamental role. Measuring handicap and quality of life must provide medical care providers with comprehensive knowledge of the way in which an individual experiences the disease, his or her handicap and the side effects and constraints of treatments within his or her own life context.
